T0 at whom it may concern.-

Be it known that I, lVIAXIMILIAN M. SUPPES, of Elyria, in the county ofLorain and State of Ohio, have invented a new and useful Improvement inBlast-Furnaces, of which the followingis a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform a part of this specification.

This invention relates to blastfurnaces,and more particularly to meansin connection with such furnaces for circulating water for the purposeof cooling the hearth-walls thereof.

The objects of the invention are mainly to provide a water-circulatingsystem which has a maximum area of cooling-surface,which will effect acirculation in proximity to the hearthwall, which is comparativelyinexpensive to construct and maintain, and in which a defeet in any partmay be readily removed or repaired and will not affect the balance ofthe system.

lVith these objects in view my invention consists in providingintermediate the hearth wall and its surrounding metallic jacket a spaceor spaces which form or are designed to contain a plurality ofindependent water conduits or channels; also, in means for supplyingwater to said conduits or channels at one end and for carrying off thewater discharged therefrom at the opposite ends.

My invention also consists in certain novel features of construction andarrangement of parts, which will be hereinafter described, and pointedout in the appended claims.

Referring to the accompanying drawings, Figure l is a front elevationshowing sections of the hearth-jacket. V Fig. 2 is a vertical sectionthrough the same, showing a portion of the hearth-wall. Fig. 3 isatransverse section on the lineX X of Fig. 1. Fig. 4 is a plan or diagramshowing the arrangement of the water-circulation pipes of a section ofthe jacket. Fig. 5 is a view similar to Fig. 2, but illustrating amodification. Fig. 6 is a section on the line Y Y, Fig. 5, lookingdownward. tively, similar to Figs. 1, 2, and 3, but showing a secondmodified construction.

In the drawings the letter A designates a portion of the hearth-wall,and B the hearthjackct, which is shown as being of the char- .scribed insaid application.

Figs. 7, 8, and 9 are views, respecacter and construction described andclaimed in my pending application, Serial No. 692,238, filed September29, 1898, and consisting of a series of metallic sections arranged inupper and lower tiers or layers contacting to form a circular jacket andprovided with means for coupling the sections together, such as thesemi-oval projections 13, which abut similar projections on adjacentsections and over which are slipped fastening devices, as de- Myinvention, however, is not limited in its application to this particularform of jacket.

The inner faces of the jacket-sections B are provided at intervals withvertical ribs Z),

I which hold said jacket away from the hearthwall and form a series ofvertical spaces,which I utilize to receive the flowing water intended tocool the hearth-walls.

The preferred form of Water circulation (shown in Figs. 2 and 3) isarranged as follows:

A short distance above the lower end of the lower layer of thejacket-sections I provide said sections with horizontal ribs c,whichproject into the spaces between the vertical ribs 17 and form shelves orledges between the hearth-jacket and the hearth-wall. On these shelvesor ledges rest a circle of independent open-end vertical pipes O, whichare held in place in sets (five being shown in each set, although thenumber is immaterial) by the vertical ribs 1).

A shelf D is formed on the outside of the hearth-wall at the upper endsof the pipes 0, thereby providing between said wall and the upperportion of the hearth-jacket an annular trough or conduit E, with whichthe open upper ends of all the pipes communicate. I also prefer toemploy a screen F, sustained by a second shelf D in the hearth-wall andthe upper ends of the ribs 1). This screen serves to prevent smallparticles of extraneous matter -such as cinder, broken pieces of bricks,&c.-from entering and choking the pipes O.

G designates a water-supply pipe which discharges intothe trough E andwhich may be in connection with the waste water from the furnace or withany suitable or convenient source of water-supply.

Below the lower ends of the pipes C the jacket is formed with verticalgrooves or channels h, and the lower layer of the jacket-sections isformed with foot portions B, which are grooved on the under side to formcommunicating channels it.

The water discharged into the trough E from the pipe Gdivides and flowsthrough the circle of pipes and escapes by way of the channels h h intoan outer trough of the furnace, (not shown,) from which it is carried tothe sewer in any desired manner.

I designates openings in the jacket just below the lower ends of thepipes. When desired, the channels h may be dammed up, leaving the spacesin the grooves h filled with water, the overflow passing out of theholes I.

It will be observed that by the construction 'described there is onlythe inappreciable thickness of the walls of the pipes 0 between thehearth-wall and the flowing water. It will also be noted that a strongwater-pressure is not required, inasmuch as the water is not obliged topass through any great length of pipe, but divides between all the pipesof the system. In case any pipe becomes defective the system as a wholeis not disturbed. The construction also provides a cooling-surface incontact with substantially the entire surface of the hearth-wall. Italso provides for the water circulation in a manner which does notprevent the jacket from forming a perfect support for the brickwork.This is of considerable importance for the reason that if the jacket isconstructed or arranged in a manner to allow movement enough to causethe brickwork to crackthe iron will follow the crack and cause abreak-out.

In the modification shown in Figs. 3 and 4 the hearth-wall is formedwith an annular recess K below the ends of the pipes, forming asurrounding chamber or trough, into which the lower ends of the pipesopen and from which also leads the outflow openings I. The grooves orchannels h h are omitted in this construction.

Figs. 7, 8, and?) show another modification, wherein the pipes O aredispensed with and the surfaces of the j acket-sections are formed witha series of alined vertical grooves M. When the jacket-sections areseated against the hearth-wall, these grooves form a series of verticalchannels or conduits, which perform the same function as the pipes C inthe first two constructions described, their open upper endscommunicating with the trough E and their lower ends communicating withgrooves or channels m in the bottom of the foot portion of the jacket.In this construction the water is in direct contact with the surface ofthe hearth-wall.

Other modifications might be obviously made without departing from thespirit and scope of my invention as pointed out in the appended claims,and I do not therefore wish to be limited to the constructions andarrangements which I have shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with the hearth-wall of ablast-furnace, of a metallicjacket surrounding the same, a plurality of independent conduits orchannels between the adjacent faces of the said wall and jacket andcontacting with both wall and jacket, and means for supplying anddischarging water to and from said conduits or channels said jackethaving portions of its inner surface intermediate of said conduits orchannels bearing against and supporting the hearth-wall.
